WebMay 23, 2024 · Ruby laser is a solid-state laser that was developed by Maiman in 1960 using Ruby as an active medium. Ruby is a crystal of Aluminium oxide. In which a part of the … The active laser medium (also called gain medium or lasing medium) is the source of optical gain within a laser. The gain results from the stimulated emission of photons through electronic or molecular transitions to a lower energy state from a higher energy state previously populated by a pump source. Examples of active laser media include:
